Final Flashcards
B mode
Straight vessel
Color and pulse wave (PW) doppler has the vessel at…
An angle
Is is important to make sure your color box is always going in the same angle as the vessel because…
A color box in the opposite direction as the vessel will give opposite flow directions
If you see color outside of the walls of the color box, you need to…
Turn down the gain
Another term for Pulse repetition frequency (PRF) is..
Scale
An excess of color during PW doppler means that the PRF is too..
Low
When the PRF is too low, is means that there’s…
Artificial aliasing within vessel
If the PRF is too high, that means that..
The color Doppler signal will fail to fill in the whole vessel
Two signs that the PRF is correct
The vessel fills in w color signal
No aliasing
Color is
Qualitative
Pulse Wave (PW) is
Quantitative
(Special analysis)
The circle in the center of a line that you use to highlight the fastest blood flow during PW doppler is called
A sample gate
The action of compressing a blood vessel inferior to the location on body being scanned is called..
Augment
Color of anything moving towards transducer
Red
Color of anything moving away from transducer
Blue
Having your angle in the same direction as your vessel during doppler for two reasons, name them
Allows color to fill in better
Gives you more accurate information in regards to which way the blood flow is moving
Leg vessels from common femoral vein to posterior tibial veins
Common femoral vein
Greater saphenous vein
Deep femoral vein
Superficial femoral vein
Popliteal vein
Posterior tibial veins
If the blood flow is going flow is needs to be sampled
Slow
The veins should always be below the…
Baseline
Moving away
The arteries should always be ______ the baseline
Above
Spectral analysis
Spectral- the tracing of whatever the waveform is
Analysis- gathering information about the blood vessel and what it is feeding / drains blood from by looking at the characteristics of it
Spectral analysis is the information by the…
Sample gate
Augmenting forces blood to move..
Faster
Fastest way to determine where the fastest blood flow is
Color doppler
How to see how accurately blood is moving you must move is the
Pulse wave / sample gate
Turn gain ______if color is showing outside of the vessel
Down
PRF needs to match how fast
blood is moving in vessel
You only augment….
